配置思路
- 在SSH伺服器上配置用戶client001和client002，分別使用不同的認證方式登錄SSH伺服器。
- 分別在STelnet客戶端Client002和SSH伺服器端生成本地密鑰對，並為用戶client002綁定ssh客戶端的rsa公鑰，實現客戶端登錄伺服器端時，對客戶端進行驗證。
- SSH伺服器端STelnet和SFTP服務使能。
- 配置SSH用戶的服務方式和授權目錄。
- 配置SSH伺服器偵聽埠號，實現客戶端以其他埠號訪問伺服器。
- 用戶client001和client002分別以STelnet和SFTP方式登錄SSH伺服器。
操作步驟
- 在伺服器端生成本地密鑰對
SSH Server:
sysname SSH Server
rsa local-key-pair create
- 配置伺服器端RSA公鑰
客戶端生成客戶端的本地密鑰對
Client002:
sysname client002
rsa local-key-pair create
查看客戶端上生成RSA公鑰。

Press CTRL + K to abort
Connected to 1.1.1.1 ...
Please input the username: client001
Enter password:
Warning: The initial password poses security risks.
The password needs to be changed. Change now? [Y/N]:n
Info: The max number of VTY users is 5, the number of current VTY users online i
s 1, and total number of terminal users online is 2.
The current login time is 2019-10-23 15:15:23.
First login successfully.
<SSH Server>
SFTP客戶端用新埠號連接SSH伺服器。
[~client002]sftp 1.1.1.1 1025
Trying 1.1.1.1 ...
Press CTRL+K to abort
Connected to 1.1.1.1 ...
Please input the username: client002
sftp-client>
- 檢查配置結果
攻擊者使用原埠號22訪問SSH伺服器，不能成功。
[~client002]sftp 1.1.1.1
Trying 1.1.1.1 ...
Press CTRL+K to abort
Error: Failed to connect to the remote host.
[~client002]
配置完成後，在SSH伺服器端執行display ssh server status命令、display ssh server session命令，可以查看到SSH伺服器端當前偵聽埠號，並且STelnet客戶端或SFTP客戶端已經成功連接到SSH伺服器。
查看SSH狀態信息。
